First weekend of March will open with a shot of snow. We are tracking a southeast bound 'clipper' system that arrives late tonight.
Happy Friday - the sunshine arrives just in time to start the weekend but as one system departs another will quickly ride into the state by sunrise.
Clouds thicken and snow will develop later tonight from northwest to southeast. We bracket the hours of 1-2 AM far northwest for the arrival of wet snow snow. Sliding southeast and temperatures rising, wet snow and possibly a mix of rain ans snow would arrive in the city between 3 and 4 am.  A quick shot of snow and rain and it all should be departing around sunrise Saturday.

Winds increase as a jet stream crosses overhead for a time late Saturday morning and early Saturday afternoon. Winds will be brisk as temperature jump to the upper 40s to near 50° in some locations. Called the 'jet max' by meteorologist is a region of strong winds blowing aloft. As the jet stream moves off to the east later in the day cooler air will once again settle in form northern Indiana. I'm posting the RPM temperature forecast at 2 PM Saturday. Could be quite a spread from north to south.

Be patient the real warmth arrive next week. Skies will brighten Sunday and with enough march sunshine we are forecasting a temperate to crack the 50° mark.
Next week we will warm and turn wet as winds at the surface and aloft originate from the Gulf of Mexico. The temperatures will reach April levels, a sting of days potentially in the 60s. The warm spell is the longest such string since early November.

Rainfall number however look hefty with numbers off two long range models from 2 to as much as 5". A large spread that has trended a little drier Convection (thunderstorms) and a stalled front could lead to the higher totals. Concern is growing for possible spring time flooding. More in the days ahead. Enjoy the weekend! (3)
